tuning problem

[02Bansheeee]

I went from clamp ons to air box w/o lid and k&n and adjusted the air screw back to factory settings. Then I attemlty to dial it in correctly and the quad will not stay running on the right side.. it keeps oil fouling the plugs. I put in New plugs and it will run fine for a few seconds then will start to bog and eventually die out on the right side. I have adjusted the screws all the way out to 2.5 turns - 1 turn out and still does it. So I figured I'm Gonna need to rejet. I'm currently running 35 pilots and 330 mains and ordered 32.5 pilots and 310 mains. The quad ran perfectly fine with the clamp ons so I'm pretty sure it isn't a spark problem, both sides have a spark. Jets will be here on Thursday or so. Can someone tell me why it would die out like that?

35 pilots are huge. What mods you have? Usually 27.5 pilots will support a decent build

clamps to box w lid?

[uman1030]

Drop down to a 30 pilot. Very doubtfull you would need anything larger with stock carbs.

 

Set air/fuel screws 1.5 out to start with fine adjust these after youve synced your carbs correctly

 

make sure idle screws are set properly so both slides are resting on the idle screw and in sync.

 

Finish syncing your carbs.

I cannot tell you.. haven't been in the engine yet. But I have t5s , air box w/ k&n without the lid, Pro design intakes, boyseen reeds, and 64.75 pistons.

[02Bansheeee]

Would those k&n clamp ons cause me to have 35s? It ran mint with them...

I would put them back on, and with my pods I'm only running 30 pilots.

My riding conditions don't allow for it. I ride in wet conditions and tend to see a lot of water. She doesn't like water.... But with the air box, she's fine.

Way way to much pilot for sure.

Run 25 pilots 27.5 max.

what air filter ya running ? Not oiled up too much ?

300 310 main for non ported should be good.

What elevation and temps ?

[02Bansheeee]

Elevation 600ft. Average temp right now is like 40-50°f.

gettn a bit cold, keep an eye on the plugs with the 310's

[02Bansheeee]

I got the jets installed. She ran good and the plugs were a dark charcoal mixed with brown. These were not new plugs. You can do plug chops with old plugs right? Or do they need to be new?

Of you're doing plug chops, use new plugs.

[02Bansheeee]

Alright, cool. And for a while it has been doing some sputtering at WTFO, it has been doing it a while, any help on why its doing that? It only does it when it wants to, not all the time. I'm gonna check the flywheel and stator and key, but it looks like both plugs have a spark about the same... Really bugs me.
